JIFFY-BAND TOOL.

Application filed February 1, 1927. Serial No. i65,074.

I as it appears in operation, and shown with p In Figure 7, I have shown a nut carrying the pivoted aw in a different position than tool, which comprises a handle 18 that is shown in Figure 1. j bent at 19 to provide an outstanding base 45 Figure 3 is a perspective view of the 20.

operator can turn nut oil of pedal shaft on to the threaded stud or stub shaft 21, which makes an easy job of a very hard one heretofore, as the nut can not be lost or dropped down out of sight when being taken off the pedal'shaft, since it issecurely located on the stud 21. In this way, the operator can remove adjusting nuts without dropping them. After the nut .or nuts are on stud 21, to replace them hold the stud 21 against end of pedal shaft, and then turn the nuts, by means of a finger, onto the shaft. With this tool, an operator can work to great advantage, because time will besaved, and the operation of taking off or placing on the nuts will be greatly simplified.

In Figures 1 and2, I have shown a transmission cover with plate removed. The tool is placed straight up orperpendicular with the pivoted jaw 9 engaging the screw or bolt 24:; this bolt 24; in Figure 1, is shown in the notch 12, with its hook lt preventing ac- In F igure 2, the bolt is positioned in the notch 13. lVhen the tool is in the position shown in Figure 1, the shank or rivet 10 will be resting in the notch 7, whereas when the tool is in the posi tion shown in F igure'2, the rivet will be in i the lower or inner end of elongated aperture 6. By reason of the peculiar forming of the teeth 15 on the edge of the flat end l1 and body of jaw 9, the tool can be placed in'an upright or vertical position. As the transmission cover is higher at front or sloping towards the back, when the tool is placed over either screw or bolt 24:"01 25, as shown in Figures 1 and 2, the peculiar construction of jaw 9, with its arrangement of teeth 15, allows the handle 1 to stand straight upright, so as to be out of the way as much as possible; also as the bands are up and down, this keeps the tool perpendicular with the bands. Q

My too-l isadapted to assume the two positions shown in Figures 3 and 5, only in Figure 3 the pawl 16 should be engaging at its outer end the innermost teeth 15. These two positions of the tool are desirable, because the transmission"cover is higher above the reverse band thanlat brake band, while raising rivet 10 in slot or aperture 6, so that it will seat in notch 7 for reverse band, and dropping rivet 10 to the lower end of slot 6, as shown in Figure 5, makes it adaptable for brake band; this adjustment makes the tool capable of removing both bands; the pawl 16 locking the tool in both positions.

It is to be noted that where the flattened portion 11 merges with the rod-like body of jaw 9, ithas the appearance of being twisted, which, when the jaw 9 is swung to its wide open position causes the outer end of pawl, 16

to engage one edge only of theflattenedend l1 and that edge is the one provided with teeth 15. i I 5 While I have described the preferred embodiment-s of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a tool of the class described, the combination of a handle, a jaw provided with bolt receiving notches pivotally mounted upon said handle, and a pawl pivotally F0 mounted on said handle and adapted to engage'said jaw.

2. In a tool of the class described, the combination of a handle provided with an elongated aperture, and having a notch at one end of said aperture, a jaw provided with teeth and a rivet, said rivet slidably mounted in said elongated aperture and adapted to be seated in said notch, and a pawl carried by said handle and adapted to engage the teeth of said jaw.

3. In a tool of the class described, the combination of a handle provided with a twisted portion terminating in a forked end. said forked end positioned at right angles EM to the handle, said handle provided near said forked end with an elongated aperture, said aperture terminating at its outer end in a notch, a jawniovable along side of said handle and provided with a rivet extending through said elongated aperture, and adapted to be seated in said notch, and a pawl carried by said handle and'adapted to engage and limit pivotal movement of said jaw.

4min a tool of the class described, the combination of a. handle, a jaw pivotally mounted on said handle, said jaw having a rod-like body and terminating at its outer end in a flattened portion, said flattened portion provided in opposite edges with notches, said flattened portion having a'hook extending inwardly at each notch, said rod-like body and flattened portion provided with teeth, said teeth on the flattened portion being located only at one edge, and a pawl pivotally mounted on said handle and adapt- .ed to engage all of said teeth.

5. In a tool of the class described, the combination of a handle, a jaw pivotally mounted upon said handle, said jaw being slightly twisted intermediate its length and formed with a flattened portion at its outer end, teeth on the upper face of said flattened portion at one edge only and also formed upon the top of the body of said jaw, said flattened portion having a, bolt receiving notch'to one side of said teeth and a second bolt receiving notch on the same side but beyond the teeth and near the outer end of the flattened portion, and a pawl -pivotally 13,0

with an inner forked end, a notched jaw, In testimony whereof I hereunto affix my mounted on said handle and adapted to ensaid jaw and pawl and through said handle, gage all of the teeth. and the pawl adapted to engage the jaw for 6.
